    about assembly optimize

      Hi, I don't want to psoc automatically optimize my code, how should I do?


      My code as following,


      WORD GetMsCount()
        WORD tmpCount;
          tmpCount = msCount;
        while(tmpCount != msCount);


        return tmpCount;

          Since msCount seems to be changed within an interrupt handler do not forget to declare it as "volatile"!!


          In Project -> Build Settings -> Compiler -> Optimization you may set "Optimization Level" to "None", this setting is best for debugging.


          Without the "volatile" attribute your while-loop would be prone to optimizatin taking tmpCount != msCount out of the loop because it does not change, leaving an infinite loop  behind.
